LG has launched a new smaller wireless charger that is compatible with the Nexus 4 smartphone.

The new device, the WCP-300, is only 6.9cm in diameter and is designed to be portable. And even with its smaller size, the charging area is 1.7 times wider than it is on LG's previous wireless charger. It is also compatible with a standard 5-pin micro-USB charger, which provides the highest level of charging performance and user convenience.

"Wireless charging is the holy grail of smartphone user convenience," said Dr. Jong-seok Park, President and CEO of LG Electronics Mobile Communications Company. "With the WCP-300, LG was able to deliver both portability with top-class charging capabilities in a device no larger than a typical beverage coaster."

The WCP-300 is compatible with both the Nexus 4 and the LG Spectrum 2 out of the box in the U.S. market. Other smartphones require the purchase of a special case in order to be charged wirelessly. LG hopes to assist in making wireless charging the industry standard by having the feature built in to most of its future devices.

Another half-orb shaped wireless charger for the LG Nexus 4 smartphone is also now available in the Google Play store.

The accessory retails for $59.99 and ships in less than one week. The charger bears a striking resemblance to the Nexus Q device that Google pulled off shelves after its initial launch last year.

Google originally announced the wireless charger for the Nexus 4 back in October. It's almost four months later and Google has finally posted it in the Play store, allowing customers to order the device. The charger can reportedly give the Nexus 4 a full charge in 4 hours time.
